Cherry Red Spot at the Macula

Cherry Red Spot at the Macula

The appearance of a "cherry red spot at the macula", caused by the contrast of a red macula against retinal pallor, occurs in a number of metabolic storage disorders, including:

Sialidosis (type I = cherry red spot-myoclonus syndrome) Gangliosidoses (e.g., Tay-Sachs disease: Tay’s sign) Metachromatic leukodystrophy
Niemann-Pick disease (especially type A)

Storage of sphingolipids or other substances in ganglion cells in the perimacular region gives rise to the appearance.
